Title: Structure of golf ball having stable rotary shaft end during flight marked on spherical surface
Inventor: KUNO TERUYA
IPC: A63B37/04
Filed: 1987-12-08
Abstract: PURPOSE: To make a golf ball fly straight to a target by reducing clockwise or counterclockwise rotary kinematics energy to fly the ball while correcting the flying line thereof by keeping it in the direction of the target. CONSTITUTION: A weight part 3 is inserted into a ball 6 to significantly decenter the center of gravity of the ball and, when the ball 6 is hit and makes a high rotation, an inertial moment of the weight part 3 works so that the ball 6 can be flown in the direction of rotation intrinsic to the ball 6. The line of a flying rotation axis 5-5' at this moment is measured to apply a 'mark' to the intersection with the spherical surface. Regarding a ball hitting method, one of the 'marks' of the stable rotation axis ends 5 and 5' of the ball 6 obtained by measurement is set toward ahead of a hitting person, and then, the ball is hit so as to maximize the inertial moment of the weight part 3.  In this process, lateral rotary motion attributed to the habitual way of the hitting person, the deformation of the ball 6 and the like is absorbed by a larger rotary inertial moment of the weight part 3. An effect thus generated accomplishes a straight flight while correcting the orbit and the ball 6 flying toward the target by straightening 'curving'.

Title: Robot hand
Inventor: TOYAMA OSAMU
IPC: B25J15/08
Filed: 1992-11-20
Abstract: PURPOSE:To control a robot with compact structure accurately by using connection links as a finger drive means for robot hand. CONSTITUTION:When a first motor 111 is driven, a force acts on a fulcrum 105a through a second connection link 105. Because the fulcrum 105a is fixed to a finger support plate 109, however, a finger rotation part 102 and a drive unit 110 are rotated by its reaction around a first shaft 121. Also, when a second motor 112 is driven, a first finger member 103 is oscillated directly around a second shaft 122. In addition, when a third motor 113 is driven, a second finger member 104 is oscillated around a third shaft 123 through third and fourth links 108 and 106. By making a combination of these three finger oscillating actions with three same kinds of fingers, work pieces of various different forms can be held. Thus, fingers can be made compact by making power transmission from a drive device through connection links to control a mechanism accurately.

Title: Tdma reception frame synchronous system
Inventor: MORI TSUNESUKE
IPC: H04L7/10
Filed: 1992-11-20
Abstract: PURPOSE:To speedily establish TDMA reception frame synchronism by permitting a control part to initialize an AFC circuit when the control signal of an AFC circuit exceeds a prescribed threshold during a continuous reception operation for establishing reception frame synchronism. CONSTITUTION:When a reference burst signal is not received after an AFC circuit 2 is energized, the control part 4 continues the reception operation as it is. Then, a carrier and the like which are not required in the period are picked up. When the control signal C of the circuit 2 exceeds the prescribed threshold + or -TH a comparison part 3 detects the state, gives information to the control part 4 and initializes the circuit 2. The control signal C of the circuit 2 is returned to a stable pull-in operation area by the initialization. When a reference burst signal is comparatively speedily received, the control signal C of the circuit 2 stably shifts in a direction where the error of a received frequency is corrected within the range of the prescribed threshold + or -TH, and the carrier wave can speedily be pulled into a transmission frequency. Thus, frame synchronism can be established.

Title: Method for brazing aluminum material
Inventor: SATO SHOICHI
IPC: B23K1/19
Filed: 1989-11-30
Abstract: PURPOSE:To simplify brazing process and to improve the productivity by adjusting the inside of a brazing furnace to an atmosphere containing fine powdery particles of chloride series flux, heating an aluminum joining member under the atmosphere at the prescribed temp., melting brazing filler metal for joining and executing the brazing. CONSTITUTION:As the coating process of suspension liquid and the drying process after coating are unnecessary at all, the brazing process can be simplified. Further, as a drying furnace is unnecessary, the equipment can be miniaturized. Since the troublesome temp. control of suspension liquid and control of coating quantity, etc., are also unnecessary, the efficiency of the whole brazing work can be improved. As the quantity of chloride series fine powdery particle acted as the flux is small compared with that of the flux used in the case of coating system, this method is economical.

Title: Magnetic recording and reproducing apparatus
Inventor: SHIOZAKI MITSUO
IPC: G11B5/024
Filed: 1994-11-24
Abstract: PURPOSE: To obtain a magnetic recording and reproducing apparatus in which a frequency used for an erasing operation does not disturb a reproducing operation while a recorded signal is erased at a small power consumption. CONSTITUTION: A magnetic recording and reproducing apparatus is provided with a signal recording means 3 by which a digital signal is recorded on a magnetic recording medium 8 and with a signal reproducing means 9 by which a recorded signal is reproduced. In the magnetic recording and reproducing apparatus, a partial-response equalization means 11 by which a reproduced signal is equalized so as to generate a specific intersymbol interference sequence and a signal discrimination means 13 by which a recorded signal is discriminated from the output of the partial-response equalization means 11 are installed. Thereby, even when a cross talk disturbance from an erasing current is mixed with a reproduced signal in a simultaneous recording and reproducing operation, it is suppressed by a partial-response equalization operation, and a signal detection is not affected at all.  In addition, since the frequency of an erasing signal becomes low, the erasing current is reduced, and a signal can be erased at a small power consumption.

Title: Analyzing pattern for semiconductor device
Inventor: KOYAMA TORU
IPC: G01R31/28
Filed: 1991-11-27
Abstract: PURPOSE:To dispense with machining performed by convergent ion beams (FIB) and facilitate indirect potential detection by providing a solitary pattern formed as the uppermost layer wiring as well as having electrical contact with lower layer wiring. CONSTITUTION:A solitary pattern 9 is formed not at the analyzing time of lower layer wiring 3 but in the manufacturing process of a semiconductor device. This formation can be made only by adding some patterns to the master patterns of an inter-layer insulation film 4 and uppermost layer wiring 5, and there is no need to add any change to the manufacturing process. At the time of analyzing the wiring 3, a passivation film 6 is removed first to detect the potential of the exposed pattern 9. Since the size of the pattern 9 is approximately the same as the width of the wiring 3, it is difficult to perform direct analysis by applying a tracer, but analysis can be performed by an indirect method of using an electronic beam tester or the like.
